Dometic RV Water Heater Board | 93865 | Non-Pilot | CSA Certified

Restore reliable ignition to your Dometic or Atwood RV water heater with the Dometic RV Water Heater Board (Part #93865). OEM Dometic ignition control circuit board — manufactured by Channel Products (same maker as Dometic's factory boards) and CSA certified for safety. Board-only replacement for non-pilot light water heater configurations. Cross-references multiple Dometic/Atwood part numbers.

⚠️ Non-Pilot Light Configurations Only

Important compatibility note: this 93865 board is engineered for non-pilot light ignition setups only. If your water heater uses a pilot light configuration, you need a different board (see the Channel Products 91363 Kit — pilot-compatible with included electrode).

⚠️ Board Only — No Ignitor / Electrode Included

This is the board-only replacement — the electrode / ignitor is NOT included. If you need a complete kit with both board AND electrode, see the Channel Products RV Water Heater Ignition Control Kit (91363) — complete pilot-light-compatible kit with both components.

OEM Dometic + Same Manufacturer as Factory Boards

Genuine OEM Dometic board — manufactured by Channel Products, the same company that produces Dometic's factory ignition boards. You're getting the exact same component-level quality and engineering as the OEM Dometic part.

CSA Certified

The 93865 is CSA certified — Canadian Standards Association certification confirms the board meets recognized North American safety standards for propane appliance ignition components. Important safety credential for a part that controls gas ignition.

Wide Cross-Reference Coverage

The 93865 board replaces multiple Dometic/Atwood ignition control part numbers:

• 93865
• 91367
• 93307
• 93253

Meaningful buyer benefit — if your failed ignition control board carries any of these part numbers, the 93865 is the direct replacement.

What This Component Does

The ignition control board handles the critical sequence that gets your water heater lit and keeps it running safely:

• Receives the call for heat from the thermostat
• Triggers the electrode to generate a high-voltage spark
• Verifies ignition and locks out if no flame is detected
• Monitors flame and gas valve operation throughout the heat cycle

Common Failure Symptoms

Reasons to replace the ignition control board include:

• Water heater won't ignite at all
• No spark trigger when heat is demanded
• Repeated ignition lockout after failed attempts
• Water heater lights but shuts off immediately
• Erratic or unreliable ignition behavior
• Unit shows no signs of operation when activated

If your electrode is also aged, cracked, or unreliable, consider the complete Channel Products 91363 Ignition Control Kit instead — includes both board AND electrode for a complete refresh.

Cost-Effective Board-Only Repair

For water heater buyers whose electrode is still in good condition but the board has failed:

• OEM Dometic board (same manufacturer as factory)
• Board-only pricing — no need to pay for an electrode you don't need
• Wide cross-reference coverage — replaces 93865, 91367, 93307, 93253
• CSA certified — meets recognized safety standards

⚠️ Professional Installation Recommended

Water heater ignition component installation should be performed by a qualified RV service technician. Improperly installed gas ignition components can result in unsafe operation, gas leaks, or fire hazards. Always verify proper ignition operation and check for gas leaks after installation.
